See the same people over and over - no way of simply saying "Not interested" - only option is to "report" the other person.
Matches don't fit search specs 100%, eg. People without photos kept appearing in my search.
WAY too expensive for what it is - doesn't even come close to Match.
Too many problems to mention.
And it's the only thing I've signed up to recently, and since I deactivated my account I get at least 50 spam emails EVERY SINGLE DAY! They all mention zoosk or sex. Very annoying.
